Secrets
There are secrets to helping you tame Google, and I'm going to share some with you after discovering them myself. So take notes ;-)
A lot of Google data goes through 2 structures, Google Play Services (most people know this) and Google Services Framework (which most people don't, because the Framework is hidden in Apps by default). When you install third-party apps they default inheriting Google Play Services' permission set.
Note that disabling the Framework also kills many things (good for me, thank you very much), such as Maps' and many other program's location abilities.
So into Android App management and then hit the hamburger (3 dots) icon on the upper right. Then tap on "Show System Apps".
Turn off all permissions on Google Play Services, then go into Data in Google Play Services and set "Restrict Background Data" to "Always". That will help kill off some of the telemetry feed.
Go and disable all permissions in Google Services Framework, then terminate the process. Then disable it.
Disable Goggle Maps (which helps feed location).
If you want to run a program that asks for your location and you want to give it, remember to re-enable Google Services Framework for the duration of the program's usage (kill it again afterwards).
There are other things I've learned, but they'll... remain a bit secret for now :P
